Lub Tsheb Wiring Harness yog dab tsi?

Lub tsheb thaiv kab hluav taws xob yog ib qho tseem ceeb ntawm lub tsheb lub tshuab hluav taws xob. Nws yog ib qho kev sib txuas hauv Circuit Court uas muaj ntau cov xov hlau, cov khoom sib txuas, cov terminals, lub tes tsho tiv thaiv, thiab lwm yam, bundled ua ke nyob rau hauv ib tug tshwj xeeb layout. Nws txoj haujlwm yog kom xa hluav taws xob zoo, cov teeb liab, thiab cov ntaub ntawv mus rau ntau yam khoom siv hluav taws xob ntawm lub tsheb (xws li lub cav ECU, sensors, teeb pom kev zoo, thiab lwm yam), ua raws li lub tsheb "lub paj hlwb." Cov hauv qab no yog cov lus piav qhia ntxaws txog lub tsheb thaiv kab hluav taws xob:

Structure thiab Composition

• Cov Hlau: Feem ntau yog ua los ntawm cov tub ntxhais tooj liab (tin{0}}plated rau oxidation tsis kam), nrog hla- ntu ntu ntawm 0.5mm² txog 6mm², cais raws li tus qauv AWG (piv txwv li, 22AWG yog haum rau qis -tam sim no cov teeb liab kis tau tus mob).
• Connectors: Waterproof hom (IP67 los yog siab dua) los yog standard hom, feem ntau yog ua los ntawm PA66 (siab-kub resistant nylon), kom ruaj khov plugging thiab kev co kuj.
• Cov ntaub ntawv tiv thaiv: Corrugated tubing, daim kab xev, los yog lub tes tsho braided, siv rau hnav tsis kam, nplaim hluav taws (UL94 V-0 standard), thiab electromagnetic shielding (xws li txhuas ntawv ci wrapping).

Cov yam ntxwv

• Qhov kub thiab txias: -44℃txog 125℃(lub cav ntim cov hlua hluav taws xob yuav tsum tiv taus qhov kub siab tshaj 150 degree).
• Voltage Level: Feem ntau low-voltage wiring harnesses (12V/24V), hos new energy motors have high-voltage wiring harnesses reaching 300V-600V (yuav tsum tau sau cov txiv kab ntxwv).
• Customized Design: Yuav tsum phim lub tsheb qhov chaw layout, optimizing routing los ntawm 3D thaiv software (xws li CATIA) kom tsis txhob cuam tshuam.

Txheej txheem ntau lawm

• Hlau Txiav thiab Crimping: Siab tsis siv neeg hlau txiav tshuab nrog qhov tseeb ntawm ± 0.5mm, thiab lub davhlau ya nyob twg crimping quab yuam yuav tsum ua tau raws li USCAR-21 tus qauv.
• Kev sib dhos thiab Kev Ntsuas: Ua qhov kev ntsuas txuas ntxiv (tsis kam tsawg dua lossis sib npaug ntawm 0.1Ω) thiab rwb thaiv tsev tiv thaiv qhov ntsuas hluav taws xob (500V AC / 1 feeb yam tsis muaj kev puas tsuaj).

Daim ntawv thov Scenario

• Cov tsheb roj ib txwm siv: Npog lub tsheb ciav hlau, lub cev tswj, infotainment, thiab lwm yam, nrog kwv yees li 1.5-2 km ntawm xaim ib lub tsheb.
• Cov Tsheb Hluav Taws Xob Tshiab: suav nrog siab - cov hlua hluav taws xob hluav taws xob (kev sib txuas roj teeb, lub cev muaj zog, thiab kev them nyiaj sib txuas), yuav tsum tau ntawv pov thawj ISO 6722-3.

Kev lag luam Trends

• Lightweighting: Aluminium hlau hloov tooj liab (txo qhov hnyav li 30%, tab sis cov teeb meem oxidation yuav tsum tau hais).
• Modularization: Zonal architecture txo cov hlua hlua ntev (piv txwv li, Tesla Model 3 xov hlau hlua tsuas yog 1.5 km ntev).
